slope = 1/2
y-intercept = 2.3
x-intercept = -4.6

Explanation:

From the slope-intercept formula:
y = mx + b

where m is the slope
and +b is the y-intercept

so

the slope is 1/2

the y-intercept is 2.3

to find x-intercept make y = 0 and solve

so

0 = 1/2x+2.3

solve for x

subtract 2.3 from both sides

-2.3 = 1/2x

multiply both sides by 2

-4.6 = x

x-intercept = -4.6
